Leah Messer Teaches Ali and Aleeah How to Be Good Sisters — See the Sweet Video!

This is too sweet! Leah Messer took to Instagram Stories to share several videos with fans of how daughters, Ali and Aleeah, make up after a fight, and it's adorable. The Teen Mom 2 star wrote, "This is what happens when two sisters fight in my home!" Watch the video above to see the clips — and to find out what else she had to say.

Aliannah, who goes by the nickname "Ali" for short, suffers from a rare form of muscular dystrophy — and her condition is getting worse. During last night's brand new episode, the reality TV mama explained to her BFF Kailyn Lowry that "her challenges are more visible than they have been before." She added, "She's been getting really, really tired, needing her wheelchair more."

The 26-year-old also revealed that Ali has been getting bullied at school. "Kids have been making fun of Ali at school to Aleeah," she said. "'Your sister walks like this.' Aleeah got angry, punched her book and was crying. Aleeah is having a hard time understanding what's going on. She needs a lot of our attention so she's being mean to Ali."

Luckily, it doesn't seem like having a disability has slowed Ali down too much. Not only has she been able to play softball and ride a bike, but she's also a good cheerleader.

Still, Leah sometimes has a hard time dealing with the stress. "I don't know how to raise a special needs child," she admitted. "This has to be the most f–ked up disorder."
